When I purchased the Kyrocera E4811 phone, it was a bit difficult to connect with Uconnect on my Chrysler 300 C. Finally I did get it to and all features messaging and such came in. Then one day the messaging goes away, It does drift in and out. and I cannot get incoming phone calls. But yet some do come in.One came in when they redialed me, I picked up on the incoming call, And some out of area calls do come in. But mostly I have to hang up on them and then call them back to return the call. It really is silly to have to do this as I have an elderly mother that calls me when she needs me and it could be simple or an emergency. Any thoughts? I would really like to get this fixed without buying a new phone. AGAIN>
